Routebase is an API lifecycle management platform built around a single living spec. It brings API design, mocking, testing, documentation, governance, and monitoring into one workflow so changes to the contract can flow through the rest of the API lifecycle.
The product is aimed at teams that want one source of truth for APIs and a way to keep frontend work, validation, docs, and agent access aligned with the same specification. The site emphasizes OpenAPI-based workflows, a stable per-project mock URL, test suites for environments and pipelines, and a built-in MCP server for AI agents.
